Simple. Scalable. Powerful.
Thermagix turns untapped heat into clean energy - quietly, efficiently, and affordably. This is the future of heat recovery.
01
What is Thermoacoustics?
Thermoacoustics is a proven heat-to-energy conversion technology, successfully used by NASA and naval forces around the world. Unlike traditional heat engines, thermoacoustic systems use sound waves as a “virtual piston”, eliminating the need for moving parts like pistons or valves.
This results in:
High efficiency
Low maintenance
Exceptional durability
Quiet and reliable operation
02
The Challenge with Existing Systems
Traditional thermoacoustic systems have demonstrated efficiencies of up to 59% of the Carnot limit - an impressive benchmark.
However, to achieve useful power densities, these systems must operate at both high pressures (typically 20–170 bar) and high temperatures, which in turn requires:
Expensive, high-performance components
Compliance with demanding safety and certification standards
Specialized materials and complex engineering
As a result, existing systems are costly to build, heavy, and difficult to scale for broader industrial use.
03
Our Breakthrough: Phase-Change Thermoacoustics
Thermagix has developed the next-generation solution: Phase-Change Thermoacoustics.
By integrating evaporation and condensation processes (phase-change) into the thermoacoustic cycle, we achieve:
-
A 100x increase in power density
-
Higher efficiency at significantly lower pressures
-
The ability to harvest heat from sources as low as 60-100℃
-
A lightweight, modular, and plug & play system design
This breakthrough dramatically reduces cost and complexity, while opening the door to low-grade heat recovery across a range of industries.
04
Why it Matters
Thermagix’s innovation makes it possible to efficiently harness low-temperature heat sources that have long been difficult or uneconomical to recover at scale.
While some technologies have addressed parts of this challenge, Thermagix redefines what’s possible - making energy recovery from previously impractical sources truly viable.
By reimagining how heat becomes power, Thermagix is paving the way toward a more efficient, scalable, and sustainable energy future.
